centos 6.5 编译安装 Python2.7 _ssl 模块编译失败

[caimaoy]

报错大概是这样的：

Python build finished, but the necessary bits to build these modules were not found:
bsddb185           dl                 imageop         
sunaudiodev                                           
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


Failed to build these modules:
_ssl

openssl.i686                       1.0.1e-42.el6_7.1                 @updates

Modules/Setup.dist 修改为如下

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto

求如何编译成功 ssl

如果没有什么练手之类的需求，建议直接安装 epel 或者 scl 里的 python27

卸载旧版 openssl，重新安装新版
